What C30 does
C30 – ENGENHARIA, AVALIAÇÕES E CERTIFICAÇÕES, LDA is a privately held Portuguese limited liability company (LDA) headquartered in Celorico de Basto with a branch office in Felgueiras, operating throughout Northern Portugal. The firm has 20 years of experience delivering integrated architecture, engineering, real estate evaluation, energy certification, and sustainability certification services under a single multidisciplinary practice. Its core offerings are organized into four pillars: architecture and engineering projects (residential houses, collective housing buildings, industrial buildings, and land subdivisions); real estate and movable property evaluations for institutional, private, and court clients; energy certifications including NZEB (Nearly Zero Energy Buildings) expertise delivered by ADENE-recognized qualified experts; and sustainability certification using the SBTOOL PT system.
The firm is registered with CMVM (registration AVFII/13/124) for real estate valuations, recognized by ADENE as a managing entity of the Energy Certification System with a PQ 146 qualified expert on staff, registered with DGaj as a court-appointed evaluator, and is a member of IISBE Portugal and the Ordem dos Engenheiros and Ordem dos Arquitetos professional associations. Professional liability insurance of €500,000 supports its evaluation work. Underlying technology is conventional professional service delivery — building design, surveying, engineering analysis, and certification — with no software platform, API, or digital product surface. The firm maintains a bilingual (Portuguese-French) website and displays a portfolio of 19 completed projects spanning its service categories.
Revenue is generated entirely through professional services on a project-by-project basis; pricing is not publicly disclosed. The customer base spans individual homeowners, real estate developers, courts and legal institutions, and institutional entities, all served through direct professional engagement rather than digital channels. The firm employs between 1 and 10 people, is privately held with no disclosed external investment, and operates with no parent company, subsidiaries, or M&A activity on record.
